I criticize Justin Bieber all the time on Twitter ... I hope he doesn't show up at my record release party.

TMZ reports that Bieber pulled up to the club and rolled down his window, which caused the crowd to go nuts. Bieber took some video of the fans and posted it to Instagram with the caption "So nice seeing my fans at the grove tonight."

He also posted a photo on Instagram of Bell looking down at Bieber's van mobbed by fans with the caption: "Why is @justinbieber sprinter van getting more attention than my album release party."
